Intersections
Why crosswalks and accessible pedestrian signals are important! Accessible Pedestrian Signals (APS) are devices that communicate information about the WALK and DON'T WALK intervals at signalized intersections, in non-visual formats, to pedestrians who are blind or have low vision.
Pedestrian issues have grown in significance over the last few decades as more people choose motor vehicles as their primary source travel. Increased transit use also reveals the need for sidewalks and other related pedestrian facilities to support safe and efficient travel.
When crossing the road, pedestrian safety is focused largely on roadway crossings since that part of the trip puts pedestrians at the most risk. Our proprietary software and smart forms allow us to collect over 30 points of data to ensure that crosswalks meet the highest standards of ADA compliance.
We survey…
Clear Space & Operational Attributes
- Clear ground space
- Push button obstruction
- Max cross/running slope
- Push button height
General APS and Detector Attributes
- Integral sign provided to identify purpose of pushbutton?
- Pushbutton clearly indicates which crosswalk actuated?
- Is an audible indication provided during the walk interval?
- Tactical arrow on pushbutton aligned parallel to the crosswalk?
High-visibility crosswalks markings
Improve on traditional crosswalks with bolder striping designs (e.g., “ladder” striping) that make the crosswalk location more obvious to motorists. High-visibility crosswalks are highly recommended at established crossings that occur in the middle of a roadway block, called midblock pedestrian crossings.
Refuge islands
Provide a raised, protected area for pedestrians to stand and wait for motorists to stop or yield while crossing the road. This solution is particularly useful when pedestrians are crossing 4 or more lanes of traffic at a midblock location.
Pedestrian crossing signs
Include yellow-and-black Pedestrian Ahead warning signs and in-street pedestrian crossing signs placed in the middle of the road. Stop Here for Pedestrians signs, installed along with painted stop bars or yield bars indicating the location motorists should stop their vehicle, provide additional warning, and guidance to motorists as they approach a marked crosswalk.
Flashing beacons
Flashing beacons can supplement crosswalks and signs to improve safety at marked crossings. A specific treatment called a Rectangular Rapid-Flashing Beacon (RRFB) uses two rectangular-shaped yellow lights that flash rapidly when a pedestrian is detected by the system or pushes a button.
